A couple of months ago, I published a post entitled A 30 minute guide to integrating Twitter in your Android application.. The post presented a sample Android application to integrate Twitter. Using the signpost library, the user was able to authorize our application to send tweets on his/her behalf. It seems that everyone is migrating to Oauth 2.0, but Twitter is still stuck at OAuth 1.0. Nevertheless, I still wanted to update the sample we did a couple of months ago for 3 reasons :

The goal of this article is to get twitter integration up & running from your Android app in 30 minutes. The guide will show you how to

setup a twitter test account

register a twitter application

authenticate the user in your Android application.

have the user send tweets from your Android application.

This guide is accompanied by a sample application that’s available in Github in the AndroidTwitterSample repository. To import this project in Eclipse, I suggest using the EGit plugin that can be installed via the Main P2 Repository located at http://download.eclipse.org/egit/updates.

Before running this project, make sure you change the com.ecs.android.sample.twitter.Constants file to include your consumer key and consumer secret. (see subsequent section).
Once you have sample application up & running, you can copy the relevant classes into your projects to have Twitter up & running.

Twitter uses the OAuth protocol to authorize your android application to send tweets on behalf of the end-user. The end-user will need to authenticate against Twitter (meaning that your application will not capture the twitter username / password). Once the user has authorized access, you’ll be able to send tweets on behalf of the user. We’ll use signpost library to handle the OAuth communication, and the Twitter4J library to handle the Twitter specific interactions (sending tweets).
